Article: Calorimetric study of nanocomposites of epoxy network DGEBA n = 0/m-XDA with gold nanoparticles Journal: International Journal of Nanoparticles (IJNP) 2014 Vol.7 No.2 pp.100 - 111 Abstract: The optimisation of cure conditions for epoxy system diglicidil ether of bisphenol A (DGEBA n = 0)/meta-xylylenediamine (m-XDA) has been made using experimental design. A quantitative analysis by Fourier transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC) as well as making of nanocomposites of epoxy system with gold nanoparticles has been carried out. The knowledge of the optimum values for the variables of experimental design obtained with DSC in the system BADGE/m-XDA allows to study the adequate conditions of the nanocomposites curing process. DSC was used to measure the glass transition temperature (T<SUB align="right"><SMALL>g</SMALL></SUB>) and the degree of conversion (α). The FTIR method should be a more precise indicator of degree of conversion than DSC and it was used to corroborate the degree of conversion.

Abstract: The optimisation of cure conditions for epoxy system diglicidil ether of bisphenol A (DGEBA n = 0)/meta-xylylenediamine (m-XDA) has been made using experimental design. A quantitative analysis by Fourier transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC) as well as making of nanocomposites of epoxy system with gold nanoparticles has been carried out. The knowledge of the optimum values for the variables of experimental design obtained with DSC in the system BADGE/m-XDA allows to study the adequate conditions of the nanocomposites curing process. DSC was used to measure the glass transition temperature (T_g) and the degree of conversion (α). The FTIR method should be a more precise indicator of degree of conversion than DSC and it was used to corroborate the degree of conversion.
